NHS Mental Health Trust are installing "Secure Units" at great expense all over the country. There is no reason for this. Restoring the originial role of the Social Worker, as was some 30 or more years ago – as part of the "social model", not the "medical model" – would replace this need.
End the use of NHS Mental Health Services as a penal system for criminals. Ill health is not the same as bad behaviour" and cannot be cured by Cognitive Behavioural Therapies. A crime against another person is exactly that – a crime.
